Run acceptance test without compiling the source code

Ugh

I did create a way, which is mainly copied from Selenium2Library project, to run acceptance test without compiling the source code. 

Although the run_acceptance_test.py indicates, jython is not supported. But perhaps it is in when jython 2.7 is out. So as a reminder, I did not remove that part. 

Also added forgotten commit from unit test to suppress keyword logging when running unit test.
